The ball breaks off the string when i tighten it

Hi
I have a new martin ooo koa. martin recommends special lights
they have an 11 on the e string. I went through ten packs today trying to string the guitar. every time I tighten the High e string the ball unravelled or popped off inside the guitar.Th pin staying in place. Finally gave up and switched out the e string with a different brand 12 gauge and it worked. Are the strings defective? The brand is Martin acoustic SP custom light.

In 55+ years I have never had that happen, even in the old days with Black Diamonds where the windings had a nasty habit unwinding. I would think it has to be either the way you are re-stringing or something inky with the strings.
